"It wasn't an X-and-O adjustment. ... They were too excited," coach Mike Krzyzewski said. "''Nuts' is the word. 'What are you guys doing?' It's not like, 'You know, you guys aren't playing hard.' They're playing hard. ... When you go like that, you're not coordinated, and it was more to get a coordinated effort on the offensive and defensive ends."
